The Association between GLP-1 Receptor-Based Agonists and the Incidence of Asthma in Patients with Type 2 Diabetes and/or Obesity:A Meta-Analysis

Objective Recent studies have indicated potential anti-inflammatory effects of glucagon-like peptide-1 receptor agonists(GLP-1RAs)on asthma,which is often comorbid with type 2 diabetes mellitus(T2DM)and obesity.Therefore,we conducted a meta-analysis to assess the association between the administration of glucagon-like peptide-1(GLP-1)receptor-based agonists and the incidence of asthma in patients with T2DM and/or obesity.Methods PubMed,Web of Science,Embase,the Cochrane Central Register of Controlled Trials,and Clinicaltrial.gov were systematically searched from inception to July 2023.Randomized controlled trials(RCTs)of GLP-1 receptor-based agonists(GLP-1RA,GLP-1 based dual and triple receptor agonist)with reports of asthma events were included.Outcomes were computed as risk ratios(RR)using a fixedeffects model.Results Overall,39 RCTs with a total of 85,755 participants were included.Compared to non-GLP-1 receptor-based agonist users,a trend of reduced risk of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments,although the difference was not statistically significant[RR=0.91,95%confidence interval(CI):0.68 to 1.24].Further Subgroup analyses indicated that the use of light-molecular-weight GLP-1RAs might be associated with a reduced the risk of asthma when compared with non-users(RR=0.65,95%CI:0.43 to 0.99,P=0.043).We also performed sensitivity analyses for participant characteristics,study design,drug structure,duration of action,and drug subtypes.However,no significant associations were observed.Conclusion Compared with non-users,a modest reduction in the incidence of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments.Further investigations are warranted to assess the association between GLP-1 receptor-based agonists and the risk of asthma.

Extraction Process and Content Determination of Total Flavonoids in Lonicera japonica

[Objectives]To optimize the extraction process of total flavonoids of Lonicerae japonica and establish a method for its extraction and content determination.[Methods]The total flavonoids of L.japonica were extracted by reflux extraction method.Through a single factor experiment,the effects of extraction method,extraction solvent concentration,extraction volume and extraction time on the total flavonoids content of medicinal materials were investigated to select the optimal extraction process of the total flavonoids of L.japonica.[Results]The optimal extraction process of the total flavonoids of L.japonica was 70%ethanol,1∶30 of solid-to-liquid ratio,and 1.0 h of reflux extraction time.[Conclusions]This method can effectively determine the content of total flavonoids in L.japonica and is expected to provide a certain scientific basis for the study of the quality standard of L.japonica.This method has high reproducibility.It is stable and feasible in extraction of total flavonoids from L.japonica.

Estimation of atherosclerotic cardiovascular disease risk in type 2 diabetes

To the Editor:The global prevalence of diabetes is increasing dramatically.[1]To prevent and treat diabetes and its cardiovascular complications,clinical practice guidelines recommend to assess the prevalent nonmodifiable risk factors in people with diabetes.The prediction for atherosclerotic cardiovascular disease(ASCVD)risk in China(China-PAR)model was specifically developed to predict the 10-year risk for ASCVD in China.

TCP1 regulates Wnt7b/β-catenin pathway through P53 to influence the proliferation and migration of hepatocellular carcinoma cells

Dear Editor,Molecular chaperones are critical mediators of oncogenesis and necessary for cell survival.1 The cytoplasmic chaperone TRiC(Tcomplex protein-1 ring complex,also known as CCT)comprises two back-to-back stacked rings,with each ring containing eight subunits(CCT1–CCT8).2 And the effects of CCT subunits on tumors may be different.However,the roles of the CCT1 subunit(also known as TCP1)in hepatocellular carcinoma(HCC)and its molecular mechanism have not been investigated thoroughly.Understanding these details can provide new ideas and strategies for treating HCC.

Cardiovascular risk profile and clinical characteristics of diabetic patients:a cross-sectional study in China

Background:Cardiovascular(CV)disease is the leading cause of morbidity and mortality in adults with type 2 diabetes(T2D).The aim of this study was to determine the CV risk in Chinese patients with T2D based on the 2019 European Society of Cardiology(ESC)and the European Association for the Study of Diabetes(EASD)guidelines on diabetes,pre-diabetes,and CV diseases.Methods:A total of 25,411 patients with T2D,who participated in the study of China Cardiometabolic Registries 3B study,were included in our analysis.We assessed the proportions of patients in each CV risk category according to 2019 ESC/EASD guidelines.Results:Based on the 2019 ESC/EASD guidelines,16,663(65.6%),1895(7.5%),and 152(0.6%)of patients were included in"very high risk,""high risk,"and"moderate risk"categories,respectively.The proportions of patients in each category varied based on age,sex,body mass index,and duration.While 58.7%(9786/16,663)of elderly patients were classified to"very high risk"group,89.6%(3732/4165)of patients with obesity were divided into"very high risk"group.Almost all patients with a duration of diabetes>10 years had"very high risk"or"high risk."However,6701(26.4%)of Chinese T2D patients,who had shorter duration,and one or two risk factors,could not be included in any category(the"unclear risk"category).Conclusions:In China,most patients with T2D have"very high"or"high"CV risk based on 2019 ESC/EASD guidelines.However,the risk of patients in"unclear risk"group needs to be further classified.
